Bifunctional electrodes with a thin catalyst layer for 'unitized' proton exchange membrane regenerative fuel cell
- Journal of Power Sources, 79(1), p.82-85, 1999 .
A bifunctional electrode structure for a unitized proton exchange membrane regenerative fuel cell has been developed. The electrode has only a thin catalyst layer; it reduces the loading of the catalyst to 0.4 mg cmy2, and minimizes mass transport and ohmic limitations. A satisfactory performance of a unitized proton exchange membrane fuel cell is achieved with this electrode structure. 50 wt.
